Okay so, I'm trying to install Ubuntu on my Lenovo B570 because my Windows screwed up saying it's missing a boot file, which is the 5th time it's happened to me. When I go to install Ubuntu, the screen is blank until I hit a key, then it sits there for a little while longer, and it shows up with a garbled command prompt screen, and I can't do anything, it just sits there. Before it starts the blankness, it says "Secure boot not enabled." Can someone please help me with this? I'm tired of being stuck with just my Chromebook...
Try to make a bootable usb. Then edit
part. Save it and restart.
